DRYING CHARACTRISTICS OF PLANT LEAVES:THEORETICAL MODELLING AND EXPERIMENTAL VERIFICATION

In the present study, a mathematical model for fast drying of mint undergoing shrinkage has been developed. Mass transfer equation is solved using a numerical technique. The material model is capable of predicting the instantaneous moisture distribution inside the material. For evaluation purposes, the model was applied to drying experiments in the range of air temperatures between 100 and 160 °C. The prediction of the average moisture content compared favorably with the experimental results. The predicted humidity ratio of a dryer also agreed fairly well with the experimental results.
